Its cool and all, but I don't think I could convince my company (and probably any other) that its worth $2/user. I think maybe there should be plans that can be hosted on the company servers. Maybe a 1 time fee to license the software and then support plans or 1 time support costs?
You can't convince your company (who is paying you thousands of dollars a month in salary) to spend an extra $2 a month on something that will make you more efficient? What kind of company do you work for?
Its worth $2/user not to have to set stuff up on my company servers. We're a small company though (6 people now) so maybe the economics are different where you are.
If it improves your productivity more than $2 a month, then its more than worth it. For us, it was a no-brainer after we started using it. Giving everyone access to everyone both asynchronously and real-time is so powerful. We used IRC and Campfire before, and neither gained as broad adoption internally.
